Why Portugal has no buyer's agents: what that means for your purchase

In Portugal, the agent showing you a property is contracted and paid by the seller. There is no licensed buyer's agent profession, no fiduciary duty to the buyer, and no legal requirement for the mediador to disclose whose interests they represent. Buyers from the US, UK, Canada, and Australia typically arrive expecting representation. In Portugal, the structural foundations for it do not exist, and understanding why matters before you sign anything.

Frequently Asked Questions

What does a buyer's agent actually do, and why does it matter in Portugal?

In the US, roughly 88% of buyers use a dedicated agent; in the UK and Australia, buyer's agents are a standard part of complex or remote purchases.

In the United States, a buyer's agent has a fiduciary duty to the buyer. That means they are legally obligated to act in the buyer's best interests, disclose conflicts of interest, and avoid placing their own financial gain above the client's needs. They search listings across all available inventory, negotiate price on the buyer's behalf, and coordinate inspections, contingencies, and closing. The buyer typically pays nothing directly. The seller's commission is split between agents through the MLS (Multiple Listing Service) cooperative infrastructure.

In the UK, buyer's agents operate similarly, sourcing properties including off-market stock, advising on price, and managing the transaction from offer to exchange. In Australia, buyer's agents are particularly common for interstate or investment purchases where the buyer cannot attend viewings in person.

The common thread across these markets: the buyer has someone whose job is to find the best property at the best price, with a legal obligation to say so if that advice costs the agent money.

None of that exists in Portugal by default.

Why Portugal never developed a buyer's agent profession

Seven structural factors prevented buyer agency from taking hold in Portugal, starting with the absence of shared listing infrastructure.

No MLS. The foundation of buyer agency in the US is the Multiple Listing Service, a cooperative database where listing agents share inventory and commissions. In Portugal, no equivalent exists. Idealista, Imovirtual, OLX, and CustoJusto are advertising portals, not shared inventory systems. Agents have no contractual mechanism to split a commission with a buyer's agent, so the economic incentive to cooperate never formed.

Open mandates. Most Portuguese sellers sign open mandates (mandato aberto), listing the same property simultaneously with multiple agencies at different prices. A buyer's agent cannot offer clients full access to the market because there is no central inventory to access. The same property may appear at €310,000 with one agency and €325,000 with another, with neither listing mentioning the other.

Commission structure. The seller pays the commission, typically 3% to 8% of the sale price, with 5% plus 23% IVA (effectively 6.15%) being the most common rate in urban markets (Savvy Cat Realty, 2025). The agency representing the seller earns this fee. There is no established protocol for splitting it with a buyer's representative, and the buyer does not pay one separately.

No legal licensing category. Lei n.º 15/2013, de 8 de fevereiro (Law 15/2013), the law governing real estate mediation in Portugal, regulates who can practice as a mediador imobiliário, not whose interests they serve. It creates no licensing category for buyer's agents and imposes no obligation to disclose which party the mediador represents in a transaction.

No fiduciary duty. The mediador's obligation is transaction facilitation. Under Law 15/2013, the mediador is responsible for identifying parties to a transaction, presenting properties, and assisting with the promissory contract. They have no legal obligation to act exclusively in the buyer's interest, provide independent price analysis, or disclose defects they have not formally verified.

Cultural norms. Domestic Portuguese buyers have operated within this structure for generations and largely do not expect independent representation. The demand for buyer agency comes almost entirely from foreign buyers importing the expectation from their home markets.

No dual agency disclosure requirement. In the US, dual agency, where the same agent represents both buyer and seller, must be disclosed and consented to. In Portugal, the same mediador routinely facilitates transactions for both parties without any legal requirement to declare the conflict.

What does the AMI licence actually authorise, and what does it leave unregulated?

The AMI licence, issued by IMPIC under Law 15/2013, authorises real estate mediation companies. It does not create any obligation to represent the buyer.

IMPIC (Instituto dos Mercados Públicos, do Imobiliário e da Construção) issues the AMI licence (Alvará de Mediação Imobiliária) to companies wishing to practice real estate mediation. As of 2025, over 11,000 valid AMI licences exist in Portugal (IMPIC, 2025).

The AMI licence confirms that a mediation company has met minimum requirements: no criminal record, a civil liability insurance policy with a minimum capital of €150,000, and proof of commercial suitability. Individual agents operate under the licence of their employer and do not require their own licence.

What the AMI licence does not do: it does not create a fiduciary duty to buyers, does not require disclosure of who the agent represents, does not obligate the agent to search the full market on a buyer's behalf, and does not regulate how commissions are split or disclosed.

A mediador with a valid AMI licence is legally authorised to practice. That is all the licence confirms.

Why does Portugal's commission structure make buyer agency economically unviable?

In Portugal, the seller pays 5% plus 23% IVA to the mediador. No standard commission-sharing mechanism exists to compensate a separate buyer's representative.

In the US, buyer agency works because the MLS creates a cooperative commission-sharing infrastructure. When a listing agent signs a seller, they agree to offer a portion of their commission to any buyer's agent who brings a buyer to the table. Both agents get paid from the seller's commission. The buyer pays nothing extra.

In Portugal, no such infrastructure exists. The mediador contracted by the seller earns the full commission. If a buyer brings their own representative to the transaction, there is no standard protocol for compensating that person. The buyer either pays the buyer's agent separately, which most buyers are reluctant to do on top of an already-expensive purchase, or the buyer's agent hopes to negotiate a commission split with the seller's agent, which happens informally at best.

This is why buyer agency never scaled in Portugal. The economic foundation was not there. Individual firms have found workarounds, charging the buyer a fixed fee or operating as consultants rather than agents, but none of these models has reached the scale of US or UK buyer agency.

The open mandate problem: same property, multiple agencies, different prices

Open mandates are the default in Portugal. A buyer comparing the same property across agencies will often find different prices, different descriptions, and no single agent who controls the listing.

In Portugal, most sellers sign open mandates with multiple agencies simultaneously. The same apartment in Lisbon may appear on Idealista listed by three different agencies at three different prices. One agency may have interior photos; another only an exterior. One may describe the property as 90m²; another as 95m².

For a buyer working with a self-described buyer's agent, open mandates create a fundamental problem: there is no guaranteed way to access all available inventory. An agent who operates within a specific network may only have relationships with certain agencies. Properties listed only with agencies outside that network may not surface.

SeaToSky Homes, an Algarve-based agency, put this plainly in their buyer guidance: they caution against buyer's agents who promise they can show a buyer every available property, because without a shared MLS, that promise cannot be kept.

Exclusive mandates (mandato exclusivo) do exist. Under these, the seller signs with a single agency for a fixed period, typically six to twelve months. The agency's incentive is clearer, and the property is more likely to be presented consistently across portals. But exclusive mandates remain less common than open mandates in the Portuguese residential market, particularly outside premium segments.

Is the agent showing you a property working for you or for the seller?

The mediador who shows a buyer around a property is, in nearly all cases, contracted by and financially accountable to the seller. No disclosure obligation exists.

When a buyer walks into a viewing arranged by a mediador, that mediador was almost certainly contracted by the seller. Their commission is paid by the seller on completion. Their professional relationship is with the seller. Yet in most transactions, that mediador is also the person answering the buyer's questions, presenting the property, and advising on whether the price is reasonable.

This is dual agency. In the US, dual agency requires written consent from both parties. In Portugal, there is no legal requirement to declare it.

The April 2025 analysis by legal firm Sérvulo, cited in Idealista, noted the absence of adequate supervision and conflict-of-interest regulation as a structural weakness of the current AMI framework. Multiple property law specialists confirmed that Portuguese legislation does not impose any obligation to disclose which party the mediador represents.

That does not make mediadores untrustworthy. Many provide good service to both parties. But the buyer should know that the person presenting the property has a financial incentive tied to the transaction completing at the highest possible price.

Who is emerging as a buyer's agent in Portugal?

A small number of firms have built buyer-focused models in Portugal, mostly targeting foreign buyers. The market is nascent, unregulated, and concentrated in Lisbon, Porto, and the Algarve.

The buyer's agent concept has gained traction among foreign buyer-focused firms over the past decade. Several operate in Portugal, each with a different model.

Goldcrest Advisers positions itself as the first locally established buyer's agent in Portugal, operating primarily in Lisbon and the Algarve. Their model: independent property search, price negotiation, and transaction coordination, financed by a buyer fee or a negotiated split with the seller's agent.

Brint Portugal operates a data-driven model focused on international buyers from the US, Canada, and the UK. They represent the buyer only, do not hold listings, and coordinate due diligence, mortgage sourcing, and relocation alongside the property search.

Pearls of Portugal, headed by Frederik Pohl, combines buyer's agent services with relocation support, covering property search, legal coordination, and post-purchase services for buyers relocating rather than purely investing.

MOL Portugal offers buyer's agent services alongside property management and post-purchase support, targeting buyers who need ongoing management after acquisition.

InspectOS does not endorse any of these firms. The market is unregulated. Any firm can describe itself as a buyer's agent, and the quality of service varies. Before engaging one, a buyer should ask: Are they charging a fixed buyer fee or hoping to split the seller's commission? Do they hold an AMI licence? Do they have verifiable transaction history in the specific location?

The counter-argument: does hiring a buyer's agent actually help?

Some experienced practitioners argue that buyer's agents in Portugal provide limited additional access to inventory and may weaken negotiating positions in certain situations.

The most articulate critique of buyer's agents in Portugal comes from practitioners who know the market well. SeaToSky Homes, whose founders built their agency after a difficult experience buying property in Portugal themselves, caution buyers against assuming a buyer's agent gives access to properties they could not find independently. In a market without MLS infrastructure, the buyer's agent cannot make inventory appear that does not already exist on the portals.

There is a subtler point too. In a market where the seller's agent controls the relationship and the commission, a buyer who arrives with their own representative may face a less cooperative seller's agent, one who sees their fee at risk of being split. In tight inventory markets, this can translate into the buyer losing the property to a less complicated offer.

Neither argument is a reason to avoid buyer's agents categorically. Both point to the same underlying issue: buyer agency in Portugal works around the system rather than through it. The value depends on the specific firm's network, the market segment, and whether the buyer needs the full relocation and coordination service or primarily needs access to properties.

For a buyer who already has a good property lawyer and an independent inspection booked, the case for a buyer's agent is weaker than for a buyer relocating internationally without local contacts.

What gap does no buyer's agent fill: physical condition of the building

Neither a buyer's agent nor a property lawyer assesses the physical condition of the building, its MEP systems, or the legal conformity of structural changes made without a licence.

This is the gap that matters most for buyers in Portugal, regardless of whether they work with a buyer's agent. A buyer's agent sources properties, negotiates prices, and coordinates legal due diligence. A property lawyer reviews title documents, contract terms, and tax obligations. Neither professional assesses structural integrity, checks for moisture intrusion, verifies electrical compliance, or identifies whether extensions or alterations have the required licences.

In Portugal, Decreto-Lei n.º 10/2024, de 8 de janeiro (DL 10/2024) removed the municipal verification step that previously caught unlicensed works before the escritura. Since January 2024, the notary no longer verifies whether a property's physical state matches its licensed description. That verification responsibility now rests with the buyer, which means commissioning it before the CPCV is signed.

A pre-purchase inspection by an Ordem dos Engenheiros (OE) registered engineer covers what no other transaction professional covers: the physical state of the building. For buyers working with a buyer's agent or those navigating the purchase alone, the inspection is the layer of protection that cannot be substituted.

When hiring a buyer's agent makes sense and when it does not

The case for a buyer's agent in Portugal is strongest for remote buyers, first-time Portugal purchasers, and complex multi-property searches in unfamiliar regions.

When it makes sense:

A long-distance purchase where the buyer cannot attend multiple viewings in person. A buyer relocating with a family who needs school catchment areas, rental market data, and contractor networks alongside the property search. An investor comparing multiple regions or property types who needs structured market analysis across a wide scope. A buyer with no local contacts who needs a trusted network of lawyers, inspectors, and mortgage brokers assembled from scratch.

When it adds less value:

A buyer who already has an established Portuguese property lawyer, a mortgage broker relationship, and is physically present for viewings. A buyer purchasing in a well-defined area with straightforward inventory where direct portal search covers the available stock. A buyer whose primary unmet need is physical due diligence, because a buyer's agent does not fill that gap regardless of the engagement.

In both cases, the property inspection is a separate need. Buyer's agents in Portugal do not conduct structural or MEP assessments, do not check for unlicensed works under DL 10/2024, and do not provide the legal-technical report that supports CPCV negotiation. That remains the domain of a registered OE engineer.

Frequently Asked Questions

Is hiring a buyer's agent in Portugal legal?

Yes. There is no law preventing a buyer from paying for representation. The AMI framework under Law 15/2013 regulates mediation companies, not who they represent or who commissions them. A buyer's agent operating in Portugal needs an AMI licence if acting as a mediation company, or may operate as a consultant. Some firms work across both models.

Does a buyer's agent in Portugal have fiduciary duty to the buyer?

No. Portuguese law does not create a fiduciary duty equivalent to what exists in the US or Australia. The mediador's legal obligations under Law 15/2013 relate to the mediation contract, not to acting in the buyer's interest. Any buyer's agent firm claiming exclusivity of representation is doing so commercially, not because Portuguese law requires it.

Can a buyer's agent show me all available properties in Portugal?

No buyer's agent can guarantee access to all available inventory. Without a centralised MLS, properties are distributed across competing portals and agencies under open mandates. A buyer's agent with a strong local network will have better access than a buyer searching portals alone, but there is no single access point to the full market.

Is the mediador required to tell me they represent the seller?

No. Law 15/2013 does not require the mediador to disclose that they are contracted by and paid by the seller. In most residential transactions, the mediador showing a buyer around a property is working for the seller's interests. The buyer should ask directly at the start of any engagement: who signed your mediation contract?

What does DL 10/2024 mean for buyers without a buyer's agent?

Decreto-Lei n.º 10/2024, de 8 de janeiro removed the notary's obligation to verify the legal conformity of a property before the escritura. This applies to all buyers regardless of whether they use a buyer's agent. Neither a buyer's agent nor a notary now checks for unlicensed works, illegal extensions, or discrepancies between the licensed description and the physical building. An independent pre-purchase inspection is the only mechanism that covers this.

Do I need both a buyer's agent and a property inspection?

These are separate services covering separate needs. A buyer's agent handles market search, price negotiation, and transaction coordination. An OE-registered engineer handles physical condition assessment, compliance verification, and defect identification. If you use a buyer's agent, you still need an inspection. If you skip the buyer's agent and navigate the purchase through a lawyer, you still need an inspection. The two do not overlap.

Conclusion

Portugal's property market does not give buyers the structural protections common in other markets. The mediador represents the seller. The law does not require disclosure of that fact. There is no shared inventory system, no fiduciary duty, and no inspection mandate. A buyer's agent can help with market navigation, particularly for remote, first-time, or complex purchases, but cannot replace the layers of legal and physical due diligence that protect buyers in Portugal.

The one gap that remains regardless of who else is on your team: physical condition. An OE-registered inspection before the CPCV is the only way to know what you are buying before your deposit is legally at risk.
